Title: API CHANGE Removed AdvancedSearchForm, extend SearchForm for custom adva...

This has been hanging around too long, for one it's very specific advanced search, and it's MySQL only.

Everyone will just customise the SearchForm themselves, so it's not necessary to have this very specific form.

Already talked to @chillu about removing this directly, instead of deprecating it. Doing a search around mailing list and forum I can't see anyone using it.

There's another pull request over at sapphire for adding this class to the "Removed classes" list in upgrade notes.
